Technical Field
[0001] This utility model relates to the technical field of gearbox manufacturing, specifically to a fixture for assembling gearbox housings. Background Technology
[0002] As a key component in mechanical transmission systems, gearboxes are widely used in various industrial equipment and civil machinery. The stability and reliability of their performance directly affect the operation of the entire mechanical system. The gearbox housing, as the basic supporting structure of the gearbox, plays a crucial role in housing and protecting internal transmission components such as gears and shafts. Its assembly quality has a vital impact on the overall performance of the gearbox.
[0003] In the manufacturing process of gearboxes, the gearbox housing is typically assembled from an upper housing and a lower housing by bolting. This assembly process requires ensuring the positioning between the upper and lower housings to guarantee the normal operation and sealing performance of the internal transmission components. Therefore, fixtures must be used to securely clamp the housing during assembly, providing a positioning reference and support for the assembly operation.
[0004] Traditional fixtures are mostly designed with fixed dimensions. However, different models of gearboxes have different designs. For example, the upper and lower housings may have different dimensions, and their length, width, and height may vary. In addition, the distribution of bolt holes is also different. The number of holes, the diameter of the holes, and the relative positional relationship between the holes may all vary. This results in poor fixture versatility, requiring each housing to be customized, which increases production costs and changeover time. Utility Model Content

[0022] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0023] First Embodiment
[0024] Please see Figures 1 to 5 As shown, a jig for assembling a gearbox housing includes a base plate 1, a fixed seat 2, a sliding seat 3, and a clamping assembly 4. The fixed seat 2 is fixedly connected to the base plate 1, and the sliding seat 3 is slidably connected to the base plate 1. Two sets of clamping assemblies 4 are provided and are symmetrically arranged and fixedly installed on the top of the fixed seat 2 and the sliding seat 3, respectively. The clamping assembly 4 includes a first telescopic rod 5, a second telescopic rod 6, a lower pressing member 7, and an upper pushing member 8. The telescopic end of the first telescopic rod 5 is fixedly connected to the lower pressing member 7, and the telescopic end of the second telescopic rod 6 is fixedly connected to the upper pushing member 8. An adjustment mechanism 9 for adjusting the distance between the fixed seat 2 and the sliding seat 3 is provided on the base plate 1.
[0025] Specifically, both the first telescopic rod 5 and the second telescopic rod 6 are electric push rods. The pressing component 7 includes a first slide rail 10 and a first slider 11. The first slide rail 10 is horizontally fixedly connected to the telescopic end of the first telescopic rod 5. The first slider 11 is slidably connected to the first slide rail 10. The bottom of the first slider 11 has a pressing groove 12 with an inverted L-shaped structure. The upper lifting component 8 includes a second slide rail 19 and a second slider 20. The second slide rail 19 is horizontally fixedly connected to the telescopic end of the second telescopic rod 6. The second slider 20 is slidably connected to the second slide rail 19. The bottom of the second slider 20 has an upper lifting groove 21 with an L-shaped structure.
[0026] When using this gearbox housing assembly fixture, first adjust the distance between the fixed seat 2 and the sliding seat 3 according to the size of the gearbox housing to be assembled, using the adjustment mechanism 9 on the base plate 1, to ensure the distance between them matches the size of the housing. After placing the upper and lower gearbox housings in the appropriate positions, activate the first telescopic rod 5 and the second telescopic rod 6 in the clamping assembly 4. The first telescopic rod 5 extends, causing the lower pressure member 7 to move downwards. Since the first slider 11 of the lower pressure member 7 can slide on the first slide rail 10, its position can be finely adjusted according to the specific shape of the housing, allowing the inverted L-shaped lower pressure groove 12 to accurately engage the corresponding part of the housing. Simultaneously, the second telescopic rod 6 extends, causing the upper top member 8 to move upwards. The second slider 20 slides on the second slide rail 19 to adjust its position, and the L-shaped upper top groove 21 positions and supports the housing from the other side. Through the coordinated action of the lower pressure member 7 and the upper top member 8, a stable clamping of the gearbox housing is achieved, providing a precise positioning reference and reliable support for the assembly operation of the upper and lower housings.
[0027] By setting adjustable spacing between the fixed seat 2 and the sliding seat 3, and the cooperation between the lower pressing part 7 and the upper lifting part 8, it can flexibly adapt to different models and specifications of gearbox housings, effectively solving the problem of poor universality of traditional fixtures. There is no need to customize fixtures for each type of housing, which greatly reduces production costs.
[0028] Second Embodiment
[0029] Based on the first embodiment, the pressing member 7 further includes a first pressure plate 13 and a first slide rod 14. The first slide rail 10 has a first slide groove 15. The first slider 11 is slidably disposed in the first slide groove 15 in a horizontal direction. The top of the first slide groove 15 has a first slide hole 16 that is vertical and faces downward. The top of the first slide rod 14 is slidably connected to the first slide hole 16, and the bottom of the first slide rod 14 is fixedly connected to the top of the first pressure plate 13. The bottom of the first pressure plate 13 abuts against the first slider 11. The pressing member 7 also includes a first anti-slip pad 17, which is fixedly disposed in the first slide groove 15. The bottom of the first slider 11 abuts against the first anti-slip pad 17. The pressing member 7 also includes a first spring 18, the top of which abuts against the first slide hole 16, and the bottom of which abuts against the first slide rod 14.
[0030] When adjusting the position of the first slider 11 according to the shape of the housing, pull the first slider 11 upwards, push the first pressure plate 13 to make the first slide rod 14 slide within the first sliding hole 16 and compress the first spring 18, so that the first slider 11 moves away from the first anti-slip pad 17. At this time, the first slider 11 can be easily slid. After the adjustment is in place, release the first slider 11. The first spring 18 rebounds and pushes the first slide rod 14, so that the first pressure plate 13 abuts the first slider 11 against the first anti-slip pad 17 to prevent its position from changing.
[0031] Third Embodiment
[0032] Based on the first embodiment, the upper pusher 8 further includes a second pressure plate 22 and a second slide rod 23. The second slide rail 19 has a second slide groove 24. The second slider 20 is slidably disposed in the second slide groove 24 in a horizontal direction. The top of the second slide groove 24 has a second slide hole 25 that is vertical and faces downward. The top of the second slide rod 23 is slidably connected to the second slide hole 25, and the bottom of the second slide rod 23 is fixedly connected to the top of the second pressure plate 22. The bottom of the second pressure plate 22 abuts against the second slider 20. The upper pusher 8 also includes a second anti-slip pad 26, which is fixedly disposed in the second slide groove 24. The bottom of the second slider 20 abuts against the second anti-slip pad 26. The upper pusher 8 also includes a second spring 27, the top of which abuts against the second slide hole 25, and the bottom of which abuts against the second slide rod 23.
[0033] When the position of the second slider 20 needs to be adjusted, pull the second slider 20 upwards, pushing the second pressure plate 22 to make the second slide rod 23 slide within the second slide hole 25 and compress the second spring 27, moving the second slider 20 away from the second anti-slip pad 26, allowing the second slider 20 to slide. After adjustment, release the pressure plate. The second spring 27 rebounds, pushing the second slide rod 23, causing the second pressure plate 22 to abut the second slider 20 against the second anti-slip pad 26, preventing position change.
[0034] Fourth embodiment
[0035] Based on the first embodiment, the adjustment mechanism 9 includes an adjustment screw 28 and an adjustment handwheel 29. A horizontal groove 30 is provided on the top of the base plate 1. The adjustment screw 28 is rotatably disposed in the horizontal groove 30. The fixed seat 2 is fixedly disposed at one end of the horizontal groove 30.

The adjustment handwheel 29 is coaxially fixedly connected to the adjustment screw 28.
[0036] When it is necessary to adjust the distance between the fixed seat 2 and the sliding seat 3, the adjusting handwheel 29 is rotated. Since the adjusting handwheel 29 is coaxially and fixedly connected to the adjusting screw 28, the adjusting screw 28 will rotate within the horizontal groove 30. The sliding seat 3 is threadedly engaged with the adjusting screw 28 through a screw hole. During the rotation of the adjusting screw 28, the sliding seat 3 will slide horizontally within the horizontal groove 30, while the fixed seat 2 is fixed at one end of the horizontal groove 30, thereby realizing the adjustment of the distance between the fixed seat 2 and the sliding seat 3.
